Application filed August 28, 1926, YSerial No. 132,253, and in GermanyIay 7, 1925.

The invention provides the hereinafter d escribed improved cleansing boxfor use in a sewerage lpipe and has for its ob]ect to provide acleansing box having an improved intercepting ydevice capable ofregulating and cutting oil an inner space.

Sewerage pipes having interior interceptent invention which consists inprovidingV the cleansing box with aninterception shut-v ter capable ofcutting off an inner space Vsaid shutter consisting of several sectorshaped metal rods arranged parallel one to the other and constructed topermit of single dismantling. v

By this special arrangement it is made possible for the independentparallel sector shaped rods,4 when the sewerage mat-ter is cleansed tobe independently taken to pieces and to be pivotally raised onlyso faras the sewerage matter to be cleansed necessitates.

Still further the device possesses the'ad-- vantage that the single rodscan bev easily cleansed and can be interchangeable.l

The invention is illustrated by way of ex'- ample in the accompanyingdrawing upon f which similar letters of reference denote cor respondingparts.

F ig. l shows the cleansing box in longi` tudinal section, and

Fig. -2 is a section taken along the line .fi-B of rig. 1.

' The cleansing box a hasA two longitudi nally connected tubes b, c, ofwhich the tube b is shutk ol'V by a rearwardly actuated piv- 46y otedvalve d whichcan be taken to pieces inthe box having two trunnions ebearing in grooves f situatedk on the inner .walls of the box.

Within the cleansing box la is an interception shutter composedofseveral independent sector formed metal rods g parallel to one another.The independent metal rods g have at their upper ends a perforation h bymeans of which they are pivoted on a bearing boltz' and are separated bydistance sleeves/2 lying adjacent the various rods. They bearing bolt z'has its ends bearing in a box-casing Z, which latter is convenientlyattached to a partition wall 'm of the box. 60

The independent sector formed rods .g normally abut against the edge 'nof afiange of the boxcasing'l.

v Havingnow described my invention what I claim and desire to secure byLettersg 1. A sewer grate comprising a supporting Y bolt, a plurality ofjuxtaposed, parallel sector-shaped-rods having toothed lower ends,

a means for suspending the upper ends of` said rods rotatablyindependently and exchangeably from said common support. l 2. Asewergrate construction comprising Z in combinationl with a partition wallofthe sewer, anda box attached thereto, a grate composed of a pluralityof-juxtaposedl sector-shaped fparallel rods, perforated near their upperends having toothed lower ends, a common bearing bolt resting with itsends in the walls of saidv box, and sleeves on said 8 bolt separatingsaid rods from each other,

said rods allowing thefree passage of the excrements or-faeces, andpreventing the passage of animals. Y i In testimony whereof I aix mysignature.
